Claim 1
Independent Claim
199 words
In a vibration generating mechanism, a lease, a vibrating member, a pair of vibration generating units connected to the vibrating member and disposed in side-by-side relation in said base, each unit having an enclosed fixed housing and having an eccentric shaft journalled within the housing, said eccentric shafts being generally parallel and corresponding ends of said shafts projecting from the respective housings, gear train means operably connecting a power source to the projecting ends of said shafts to rotate said shafts in opposite directions, said gear train means including a pair of first gears connected to the projecting ends of the respective shafts and a pair of second gears interconnecting said first gears, a gear casing connected to said housing and containing said gear train means, a shift mechanism disposed within the gear casing and outside said fixed housings and operable to effect angular displacement of a first of said shafts relative to the other of said shafts to thereby provide an adjustment in the angularity of forces generated and reverse movement for said vibrating member, and operating means connected to the shift mechanism and disposed on the outside of said gear casing for manually operating said shift mechanism.

In a vibration generating mechanism, a lease, a vibrating member, a pair of vibration generating units connected to the vibrating member and disposed in side-by-side relation in said base, each unit having an enclosed fixed housing and having an eccentric shaft journalled within the housing, said eccentric shafts being generally parallel and corresponding ends of said shafts projecting from the respective housings, gear train means operably connecting a power source to the projecting ends of said shafts to rotate said shafts in opposite directions, said gear train means including a pair of first gears connected to the projecting ends of the respective shafts and a pair of second gears interconnecting said first gears, a gear casing connected to said housing and containing said gear train means, a shift mechanism disposed within the gear casing and outside said fixed housings and operable to effect angular displacement of a first of said shafts relative to the other of said shafts to thereby provide an adjustment in the angularity of forces generated and reverse movement for said vibrating member, and operating means connected to the shift mechanism and disposed on the outside of said gear casing for manually operating said shift mechanism.
Claim 3
Dependent Claim
107 words
The mechanism of claim 1, wherein said gear means comprises a gear journaled about the projecting end of said first shaft and having a first driving element, a ring spaced axially from said gear and fixed to said gear and having a second driving element, and a shift member rotatably connected to said first shaft and axially movable relative to said first shaft, said shift member having a lug selectively engageable with said first and second drive elements, said operating means being connected to said shift member to move said shift member axially of said shaft and provide selective engagement of said lug with said driving elements.
Claim 4
Dependent Claim
21 words
The mechanism of claim 2, wherein the first driving element is displaced in a circumferential direction of said second driving element.
Claim 5
Dependent Claim
19 words
The mechanism of claim 3, wherein said first driving element is displaced approximately 180° from said second driving element.
Claim 6
Dependent Claim
27 words
The mechanism of claim 2, wherein said operating means comprises a rod extending through an opening in said gear casing and operably connected to said shift member.
